WTD: Tandberg Huldra 12 service data

[stevehertz]

I'm looking for Tandberg 'Huldra 12' service data. It's a multi band receiver and was the last in the great line of Huldra receivers. It's predecessor or at least a very similar model (which was not named Huldra!) is the TR2025. I have the full service data for that set but it is not the same, I've tried to use it and it doesn't work. I need realignment information. If anyone can help or have any suggestions as to where this data may lie, please let me know, thanks. I have basic schematics (available from Hifi Engine and Radiomuseum), but I need the full manual to do what I want to do.

You've directed me to schematics there Ben?

Apologies, I mistook the content of that link, have deleted it. Hope the FB place yields something!

Thanks for the useful link, but it only has schematics for the Huldra 12.

Many thanks, I've dropped him an email. Fingers crossed!

Thanks Ben. Yes I'd forgotten about the Facebook Tandberg pages. There's actually three different ones and I've used them before. I've posted a message on all three.

Ahh.. Just realised, it's Chris Reynard. I've already sent him a request, I know him by name not his business. Never mind that's two emails he'll receive!

Is it possible that the Huldra 11 SM was still applicable, and all that was issued was the updated schema?

I very much doubt it Richard. The TR2025 you would take to be a clone in many, man ways, but the circuity is different in places, especially the FM side. I've done enough messing about trying to match it to circuits from other sets! But thanks for the idea.

I have discovered that the TR2025 and the Huldra 11 are the same receiver. Maybe different names for different markets, I don't know. Anyway, the data for those sets is not, for my purpose, of use. I have it already and it doesn't match. I'm currently working on 'the theory' that the FM side is the same as is used on the TR2080 as they're the same era, and I do have data on 2080.

I have managed to sort out the FM side of the Huldra 12. At the very end of the Huldra 11 service data it mentions a revised FM module that it calls FM 4, and it gives the physical layout including the adjustment coils and caps. Sure enough, it tallies with my Huldra 12. So I was able to tweak the oscillator to obtain dial accuracy that was not there before. The Huldra 11's MW side seems to be the same as the 12 and I have made improvements to it with a few learned tweaks of coils and caps. However, just like the FM side, LW does not tally with the Huldra 12's circuitry or layout. So, I'm still needing the Huldra 12 service data to adjust LW. At present BBC R4 is peaking at around 185KHz, not 198. I have tried a few tweaks trying to 'interpret' the 11's data but it's not budging, so clearly there's more info needed. But we're getting there.
